Corbin Russwin 684F427 – Frequently Asked Questions

1) Will this rod extension kit work on a surface vertical rod or rim exit device?
No. The 684F427 kit is built for concealed vertical rod devices in the Corbin Russwin ED4000 and ED5000 Series. A rim device such as the ED5200 latches into a surface strike and has no vertical rods at all, and a surface vertical rod device like the ED5400 uses exposed rods of a different construction. Match the kit to a concealed vertical rod opening.
2) My ED5000 device is on a 4-1/2 inch stile aluminum door - is that a problem for adding rods?
4-1/2 inch (114mm) is the minimum stile width the ED4000/ED5000 family is rated for, so you are right at the limit but within it. Door thickness is 1-3/4 inch (44mm) standard for the line, with 2 inch (D200) and 2-1/4 inch (D214) options. If your door is thicker than 1-3/4 and the original device was not ordered with those suffixes, that is a bigger issue than rod length.
3) Will a Design Hardware exit alarm kit or cylinder dogging kit fit my Corbin Russwin ED5000?
No. The Design Hardware alarm kits and cylinder dogging kit are made for Design Hardware 1000 and 2000 Series exit devices. On Corbin Russwin ED4000/ED5000 hardware, dogging is handled by the device itself - single-point 1/4-turn hex key standard, with cylinder dogging or electric dogging as factory options - and electrified functions like delayed egress and electric latch retraction are ordered on the device, not added by a third-party kit.
4) For a pair of doors, should I use a rod extension kit or a removable mullion?
Those are two different approaches to a double door opening. The Corbin Russwin 684F427 is used when concealed vertical rod hardware is already the plan and the door is taller than the standard rod length covers, adding 24 inches of rod reach to ED4000 and ED5000 Series concealed vertical rod devices. A BEST Precision KR822689 key removable mullion is a 2 inch by 3 inch by 8 foot aluminum mullion that stands between the two leaves so rim devices can be used instead of vertical rod devices, and it can be keyed out when the full opening width is needed. If the openings keep their concealed vertical rod devices, the extension kit is the part that matches; if the design is moving to rim devices on a pair, the mullion is the path.
5) Does adding this extension kit affect the fire rating on my ED5000 exit device?
The ED4000/ED5000 exit devices are UL/cUL listed as panic and 3-hour fire exit hardware and are built to NFPA 101 and NFPA 80. Using the manufacturer's own 684F427 extension kit keeps you on factory parts, which is what a fire-rated assembly requires. Shop-fabricated rod extensions are what get an opening written up.
6) What grade is the Corbin Russwin ED4000/ED5000 exit device hardware this kit belongs to?
ANSI/BHMA A156.3 Grade 1, which is the heaviest commercial duty level for exit devices and the usual spec on schools, hospitals, and government openings. The line is also California State Fire Marshal approved and ADA compliant on its lever trims and pulls.
7) Is the 684F427 rod extension kit handed?
ED4000/ED5000 devices are non-handed as standard, with handing only coming into play on lever trim and double cylinder configurations. A rod extension runs vertically in the door edge, so there is no left or right hand version to specify here - you are specifying length, 24 inches, and finish.
8) Can I just field cut a longer rod instead of buying an extension kit?
The push bar on ED4000/ED5000 devices is the part meant to be field cut - it ships 36 inches to fit 30 to 36 inch doors, with 24 inch and 48 inch options. The vertical rods are a different matter: latching depends on exact rod reach at top and bottom, so use the 684F427 24 inch extension rather than improvising, especially on a fire rated opening.
9) What other service parts do buyers add to exit devices besides rod extensions?
Depends what you are solving. To secure a pair of doors without concealed rods, a removable mullion like the BEST Precision KR822689 (2 x 3 inch, 8 foot, aluminum) lets you run two rim devices instead. To add local alarm on an egress door, Design Hardware sells exit alarm kits for its 1000 and 2000 Series devices. To hold a door pushed-open during business hours by cylinder, Design Hardware offers a cylinder dogging kit for the 1000 Series. Note those kits are brand-specific and do not mount on Corbin Russwin hardware - on the ED4000/ED5000 you specify dogging through the device itself, which comes with 1/4-turn hex key dogging standard and cylinder or electric dogging as options.
10) Is the Corbin Russwin 684F427 rod extension kit interchangeable with a Design Hardware cylinder dogging kit?
No, they solve different problems. The Corbin Russwin 684F427 is a 24 inch rod extension kit that extends the height of standard length rods on ED4000 and ED5000 Series concealed vertical rod exit devices so the rods reach the top and bottom latch points on a taller door. The Design Hardware DH-CD-1000 is a cylinder dogging kit for Design Hardware 1000 Series exit devices, which changes how the device is held in the dogged position rather than addressing rod length. The Corbin Russwin ED4000/ED5000 devices already use single-point 1/4-turn hex key dogging with optional cylinder or electric dogging, so a Design Hardware dogging kit is neither a fit nor a substitute.
11) I need a part for a Design Hardware 1000 or 2000 Series device - does the 684F427 work?
No. The Corbin Russwin 684F427 rod extension kit is built specifically for Corbin Russwin ED4000 and ED5000 Series concealed vertical rod exit devices and is dimensioned to those rod assemblies. Accessories catalogued for Design Hardware devices are series-specific in the same way, with the DH-CD-1000 cylinder dogging kit and DH-ALK-1000 exit alarm kit both called out for 1000 Series devices and the DH-ALK-2000 exit alarm kit for 2000 Series devices. Match the accessory to the device family already on the door.
12) What finishes does the 684F427 rod extension kit come in?
Three choices: 613 Satin Bronze Oil-Rubbed, 630 Satin Stainless Steel, and an unfinished version. On a concealed vertical rod opening the rods sit inside the door edge, so unfinished is usually fine unless you want the exposed hardware to match 613 or 630 trim already on the other doors in the building.
13) How much does an ED5000 exit device project off the door face when I am checking clearance?
3-1/4 inches (83mm) in the active position and 2-3/4 inches (70mm) when dogged down. Worth checking against a corridor width or an adjacent wall before you commit to this line on a tight opening.
14) Will an exit alarm kit do anything to fix a rod that is too short?
No. Design Hardware exit alarm kits such as the DH-ALK-1000 for 1000 Series devices and the DH-ALK-2000 for 2000 Series devices add local alarm function to those exit devices; they have no effect on rod reach or latching. When a concealed vertical rod device is not engaging its top and bottom latch points because the door is taller than the standard rod covers, the Corbin Russwin 684F427 24 inch rod extension kit for ED4000 and ED5000 Series devices is the part that addresses it. The two can coexist on a project, but one does not stand in for the other.
